Hello,

I have a win7 ultimate box with intel i7 950 cpu, sabertooth x58 mobo, 8 GB ram.

I am looking for a new graphics solution and have no idea here. I am debating between the two setup and need some feedback

Setup 1: GeForce GTX 650TI 2GB card

Setup 2: 2 Radeon 5850 1GB Cards

I am not looking at cost as a factor. I only need peformance based feedback. Thanks

Different versions are not significantly different, they are all in 5% range. Sapphire, evga, msi, asus, xfx, gigabyte, HIS are reputable manufacturers, get anyone of these brands whichever is cheaper

I believe you are misunderstanding my question. I am wondering if it will make a large difference to have 2 of the Radeon 5850 cards vs one of the GTX 650Ti card. The Radeon cards will be setup with crossfire, I am not aware of the benefits of the crossfire setup.

Sorry i have not read 2x5850. In that case 2x5850~760 which is way better than a single 650ti(almost double the performance) but there are lag problems with crossfire setup even with the latest drivers and crossfire will consume a lot of power and generate a lot more heat. Read this article

What is ur total budget? If u have one 5850 I recommend u to sell it and get one 7950/GTX760.

Hi Sleepinfire,

Ok I will point a few things out since you asked about performance between the 650 Ti
and the 5850 cards in a crossfire setup.

The 650 TI card only has what we call a 128 bit memory bus.
A 5850 card has a 256 bit memory bus.

There is no contest, a 128 bit interface will choke the card or should I say the potential of a Gpu.
That is why when you look at the cards the texture fill rate of the 5850 card is higher,
this is because of the 256 bit wide memory bus.

For one 5850 card Performance is around or even better than the 2013 Radeon HD 7790, and is suitable for a 1080p resolution, but some Modern Demanding games like Crysis 3 will need lowered Aliasing settings to be playable. Its power consumption is considerably higher than other GPUs

With a crossfire 5850 setup you will get around an extra 40 % more raw power, than a single 5850 setup.

I would go the route of the two 5850 cards, there is no contest.
Not in my mind.
